Valve stem seals play a critical role in engine performance by precisely controlling the amount of oil that lubricates the valve stem as it moves in the valve guide. Too little oil causes premature wear of stems and guides, while excessive oil leads to increased consumption, carbon buildup on valves and pistons, rough idle, and potential catalytic converter damage. The Federal Mogul SS72629 seal set uses premium materials selected specifically for the application to ensure proper oil metering, heat resistance, and long service life.

The included installation tool is a thin plastic sleeve that slides over the valve stem tip, protecting the seal's inner lip from damage caused by the valve keeper grooves during installation. This simple but essential tool helps ensure proper seal installation and prevents premature failure.
